Saft has been awarded a multi-million dollar contract from Boeing to build Li-ion battery packs for four new 702SP communications satellites. The technology-rich “small platform” satellites, designed to operate in the 3- to 8-kilowatt power range, are being developed by Boeing for Asia Broadcast Satellite (ABS) and Satélites Mexicanos (Satmex).

The first two satellites, ABS-3A and Satmex 7, are scheduled to be completed by Boeing in early 2015 and launch together on a SpaceX Falcon 9 rocket. Saft will deliver batteries in 2013-2014 from its Cockeysville, MD Space & Defense Division factory. This is the first order for Boeing’s 702SP satellite program.

Saft will deliver multiple battery cells for each satellite. Each battery contains lithium-ion cells and modules with the batteries supplying 8 kW of on-board power during its 15-year life. This battery power is delivered primarily during the two 45-day eclipse periods each year while in GEO satellite orbit.

This is the fourth order from Boeing for commercial satellite batteries since signing a long-term agreement with Saft in 2009. The projects will also add to Saft’s total kilowatt hours in space and further establish the heritage of the high energy battery packs, which are used to power the Boeing 702 satellite programs (including Intelsat, Inmarsat, SkyTerra and MEXSAT).
